Analog and Digital Converters - Technical MCQs

Q1:

A binary-weighted digital-to-analog converter has an input resistor of 100 komega.gif. If the resistor is connected to a 5 V source, the current through the resistor is:

A 50 mu.gifA

B 5 mA

C 500 mu.gifA

D 50 mA

ANS:A - 50 mu.gifA

I=V/R
I/P resister has 100k=100000,k=1000
resister has 5v,v=5
I=5/100000
I=.00005,micro amp=10^-6
I=50microA
